Before I drive myself mad and try to build something I'm incapable of…

Has anyone built an #ActivityPub server for embedded devices?

Not a Raspberry Pi, but like one of those tiny ESP32 devices which can run MicroPython or similar.

I built a *full* AP server in around 64KB of PHP
https://gitlab.com/edent/activity-bot/

Now I'm wondering if a tiny sensor could be a fully-fledged ActivityPub node on the Fediverse.
